It all started after the last battle at the arena. Sonic decided to go back to Equestria (with shadow wanting adventure too he really couldn't say no either) to have new adventures there but X let him bring back Tails and Knuckles with him to Equestria. Also Sonic was pending on a new found love now that Amy wasn't chasing him where ever he went.So let the adventure, Begin!

As Sonic and friends got to Equestria with the ponies he decided to take a look they showed them around Canterlot just because they appeared there first and they took a train ride back to PonyVille.So after that when they got back Rainbow Dash still had some unfinished business with Sonic, they still had to finish there race.

As Rainbow Dash showed them her friends as they went to a tree house "Here is my friend Twilight." Rainbow said as she opened the door immediately she turned around saying, "Rainbow you know this is my study hour." sounding annoyed. "Every hour is study hour for you egghead!" Rainbow said. Tails immediately said, "Is studying bad?" Twilight noticed he was a little of a brainiac too. "Finally some pony gets what i'm saying well i guess not a pony but," Twilight said but Rainbow interrupted by saying, " Well not a pony, but a two tailed fox's approval."

"Well lets just get all of them really fast to talk at twilight's place for a New Friend Party." right after Rainbow said Party a bright pink pony came up and started greeting Sonic and his friends very quickly, then ran off to make a Welcome To PonyVille Party Sonic thought she said.

Later night at Twilight's house they soon got down to the party and they soon met Pinkie Pie, the bright pink colored mane, tail, and skin;crazy party pony that they met earlier, Apple Jack, orange skinned and a blond main and tail;friendly farm pony, Flutter Shy, a soft and gentle yellow skinned pony with a pink mane and tail, and Rarity, a beautiful snow white skinned pony with a purple mane and tail.

After the party Sonic and friends wondered were they would sleep. Flutter Shy wanted Tails to come to her cottage because she had never seen a fox with two tails so Tails didn't care. Then Apple Jack thought Kuckles might help in the morning with harvesting some apples so knuckles didn't care either. Then Sonic he decided to sleep up in CloudsDale with the soft fluffy clouds. (He also wanted to be by Rainbow Dash.) Then Shadow wanted to stay with Twilight because Shadow loves stars and Twilight has a telescope so they said there good byes until tomorrow morning.
